50-degree circularly polarized conical beam antenna with 2.15 GHz frequency

[0024] Such as figure 1 As shown, a 50° circularly polarized cone beam antenna with a frequency of 2.15GHz includes a cylindrical support structure 1, an arm 2 arranged at the top of the cylindrical support structure, and a reflector 3 arranged at the bottom end of the cylindrical support structure. The cylindrical support structure includes inner and outer layers, and a feeder line 4 is arranged inside, and the reflection plate is a disc filled with distilled water.

[0025] In a further embodiment, the outrigger arms are divided into two groups, and the outrigger arms in the same group are arranged directly opposite to each other. The outrigger arms include horizontal columns and inclined columns, and the total length of the horizontal columns is 10mm. The length of the column inserted in the horizontal direction is 3mm, and the length of one set of inclined columns with outstretched arms is 28mm, and the length of the other set of inclined columns with outstretched arms is 18m
